| 1 | Gastrointestinal imaging-practical magnetic resonance imaging approach显示文摘Over the past two decades, advances in cross-sectionalimaging such as computed tomography and magneticresonance imaging(MRI) have dramatically changed theconcept of gastrointestinal imaging. MR is playing anincreasing role in the evaluation of gastrointestinal disorders. MRI combines the advantages of excellent soft-tissue contrast, noninvasiveness, functional informationand lack of ionizing radiation. Furthermore, recent developments of MRI have led to improved spatial and temporal resolution as well as decreased motion artifacts. Inthis article we describe the technical aspects of gastroin-testinal MRI and present a practical approach for a well-known spectrum of gastrointestinal disease processes. | Baodong Liu Miguel Ramalho Mamdoh AlObaidy Kiran K Busireddy Ersan Altun Janaka Kalubowila Richard C Semelka | 2014 | World Journal of Radiology2014，6，8： | 11 |
| 2 | Magnetic resonance imaging of pancreatitis: An update显示文摘Magnetic resonance(MR)imaging plays an important role in the diagnosis and staging of acute and chronic pancreatitis and may represent the best imaging technique in the setting of pancreatitis due to its unmatched soft tissue contrast resolution as well as nonionizing nature and higher safety profile of intravascular contrast media,making it particularly valuable in radiosensitive populations such as pregnant patients,and patients with recurrent pancreatitis requiring multiple follow-up examinations.Additional advantages include the ability to detect early forms of chronic pancreatitis and to better differentiate adenocarcinoma from focal chronic pancreatitis.This review addresses new trends in clinical pancreatic MR imaging emphasizing its role in imaging all types of acute and chronic pancreatitis,pancreatitis complications and other important differential diagnoses that mimic pancreatitis. | Sriluxayini Manikkavasakar Mamdoh AlObaidy Kiran K Busireddy Miguel Ramalho Viragi Nilmini Madhavi Alagiyawanna Richard C Semelka | 2014 | World Journal of Gastroenterology2014，20，40： | 8 |
| 3 | Focal liver lesions:Practical magnetic resonance imaging approach显示文摘With the widespread of cross-sectional imaging, a growth of incidentally detected focal liver lesions(FLL) has been observed. A reliable detection and characterization of FLL is critical for optimal patient management. Maximizing accuracy of imaging in the context of FLL is paramount in avoiding unnecessary biopsies, which may result in post-procedural complications. A tremendous development of new imaging techniques has taken place during these last years. Nowadays, Magnetic resonance imaging(MRI) plays a key role in management of liver lesions, using a radiation-free technique and a safe contrast agent profile. MRI plays a key role in the non-invasive correct characterization of FLL. MRI is capable of providing comprehensive and highly accurate diagnostic information, with the additional advantage of lack of harmful ionizing radiation. These properties make MRI the mainstay for the noninvasive evaluation of focal liver lesions. In this paper we review the state-of-the-art MRI liver protocol, briefly discussing different sequence types, the unique characteristics of imaging non-cooperative patients and discuss the role of hepatocyte-specific contrast agents. A review of the imaging features of the most common benign and malignant FLL is presented, supplemented by a schematic representation of a simplistic practical approach on MRI. | António P Matos Fernanda Velloni Miguel Ramalho Mamdoh AlObaidy Aruna Rajapaksha Richard C Semelka | 2015 | World Journal of Hepatology2015，7，16： | 6 |
| 4 | Pancreatitis-imaging approach显示文摘Pancreatitis is defined as the inflammation of the pancreas and considered the most common pancreatic disease in children and adults. Imaging plays a significant role in the diagnosis, severity assessment, recognition of complications and guiding therapeutic interventions. In the setting of pancreatitis, wider availability and good image quality make multi-detector contrastenhanced computed tomography(MD-CECT) the most used imaging technique. However, magnetic resonance imaging(MRI) offers diagnostic capabilities similar to those of CT, with additional intrinsic advantages including lack of ionizing radiation and exquisite soft tissue characterization. This article reviews the proposed definitions of revised Atlanta classification for acute pancreatitis, illustrates a wide range of morphologic pancreatic parenchymal and associated peripancreatic changes for different types of acute pancreatitis. It also describes the spectrum of early and late chronic pancreatitis imaging findings and illustrates some of the less common types of chronic pancreatitis, with special emphasis on the role of CT and MRI. | Kiran K Busireddy Mamdoh AlObaidy Miguel Ramalho Janaka Kalubowila Liu Baodong Ilaria Santagostino Richard C Semelka | 2014 | World Journal of Gastrointestinal Pathophysiology2014，5，3： | 4 |
| 5 | Predicting early outcomes of liver transplantation in young children: The EARLY study显示文摘AIM To determine potentially modifiable predictors of early outcomes after liver transplantation in children of age < 3 years.METHODS This study was a retrospective chart review including all consecutive children of age less than 3-years-old having had a liver transplant done at the Western Canadian referral center from June 2005 to June 2015.Pre-specified potential predictor variables and primary and secondary outcomes were recorded using standard definitions and a case report form. Associations between potential predictor variables and outcomes were determined using univariate and multiple logistic [odds ratio(OR); 95%CI] or linear(effect size, ES; 95%CI) regressions. RESULTS There were 65 children, of mean age 11.9(SD 7.1) mo and weight 8.5(2.1) kg, with biliary-atresia in 40(62%), who had a living related donor [LRD; 29(45%)], split/reduced [21(32%)] or whole liver graft [15(23%)]. Outcomes after liver transplant included: ventilator-days of 12.5(14.1); pediatric intensive care unit mortality of 5(8%); re-operation in 33(51%), hepatic artery thrombosis(HAT) in 12(19%), portal vein thrombosis(PVT) in 11(17%), and any severe complication(HAT, PVT, bile leak, bowel perforation, intraabdominal infection, retransplant, or death) in 32(49%) patients. Predictors of the prespecified primary outcomes on multiple regression were:(1) HAT: split/reduced(OR 0.06; 0.01, 0.76; P = 0.030) or LRD(OR 0.16; 0.03, 0.95; P = 0.044) vs whole liver graft; and(2) ventilator-days: surgeon(P < 0.05), lowest antithrombin(AT) postoperative day 2-5(ES-0.24;-0.47,-0.02; P = 0.034), and split/reduced(ES-12.5;-21.8,-3.2; P = 0.009) vs whole-liver graft. Predictors of the pre-specified secondary outcomes on multiple regression were:(1) any thrombosis: LRD(OR 0.10; 0.01, 0.71; P = 0.021) or split/reduced(OR 0.10; 0.01, 0.85; P = 0.034) vs whole liver graft, and lowest AT postoperative day 2-5(OR 0.93; 0.87, 0.99; P = 0.038); and(2) any severe complication: surgeon(P < 0.05), lowest AT postoperative day 2-5(OR 0.92; 0.86-0.98; P = 0.016), and split/reduced(OR 0.06; 0.01, 0.78; P = 0.032) vs whole-liver graft. CONCLUSION In young children, whole liver graft and surgeon was associated with more complications, and higher AT postoperative day 2-5 was associated with fewer complications early after liver transplantation. | Rashid Alobaidi Natalie Anton Dominic Cave Elham Khodayari Moez Ari R Joffe | 2018 | World Journal of Hepatology2018，10，1： | 2 |
